tourist information

tourist information n.  Information in an on-line display
   that is not immediately useful, but contributes to a viewer's
   gestalt of what's going on with the software or hardware behind it.
   Whether a given piece of info falls in this category depends partly
   on what the user is looking for at any given time.  The `bytes
   free' information at the bottom of an MS-DOS `dir' display is
   tourist information; so (most of the time) is the TIME information
   in a UNIX `ps(1)' display.
